Exploring the use of Event Based Imaging Sensors on Turbulence Characterisation and Adaptive Optics
Abstract
This project seeks to explore the potential applications in adaptive optics for a specific class of non-traditional imaging device known as neuromorphic event-based cameras. These devices make use of custom silicon devices with in-pixel circuitry that produce data only in response to changes in log-illumination. The device therefore does not produce frames and does not require fixed integration times, rather producing data in the form of a spatio-temporal event stream with a very high temporal resolution. This work seeks to apply these devices in the field of adaptive optics to assess their ability to provide novel and high-speed operation. The proposed research will use an adaptive optic testbed centred around a conventional Shack-Hartmann wavefront sensor, to validate conventional approaches applied to event-based sensors. The results of these experiments will then drive the development of new methods specifically designed for event-based cameras and making use of neuromorphic design principles.
